NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent n5. 590,054, datedSeptember 14, 1897.

Application filed October 30, 1896. Serial No. 610,603. (No model.)

i To all when it may concern: I

Be it known that I, JACOB M. DOOLI'r-TLE,

a citizen of the United States of America, rcsiding at New Kensington,in the county 'of lVestinoreland and State of Pennsylvania,

have invented certain new and useful Improvements in Non-RefillableBottles, of which the following is a specification, refer ence being hadtherein to the accompanying drawings.

This invention relates to certain new and useful improvements innon-refillable bottles, and has for its object to construct a bottlethat when once filled and the plunger inserted in the neck of same willpermit the ready outflow of the liquid, but will prevent any addi tionalliquid being introduced into the bottle or filling the same after theoriginal contents have been removed.

The invention further aims to construct a bottle of this class that willbe extremely simple in its construction, strong, durable, and effectualin its operation, and comparatively inexpensive to manufacture, addingbut a few cents per gross to the original cost of the bottles.

lVith the above and other objects in view the invention finally consistsin the novel construction, combination, and arrangement of parts, to behereinafter more specifically described, and particularly pointed out inthe claim.

In describing the invention in detail reference is had to theaccompanyingdrawings, forming a part of this specification, wherein likeletters of reference indicate similar parts throughout the severalviews, in which plunger consists of the stem at and capdiead e, whichare composed, preferably, of hard rubber or similar material, said stembeing provided with a weighted portion f and the cap-head being providedwith a metal or other bottle.

able bottle will be readily apparent from the views of the same that Ihave shown in the drawings, but in order to illustrate same more clearlyto those unskilled in the same I will describe it as follows: The bottleis filled with the liquid and the plunger of stopper placed in the neckof the same and forced downward, the stem passing down into thebottle-neck and the head or cap engaging in the groove 1), the flexiblematerial of which said cap or head is composed permitting the samepassing into the groove, as it will be observed, by reference to Fig. 2of the drawings, that the metal covering is not as great incircumference as the head (2. When this plunger is inserted in the neckof the bottle, it will be impossible to remove the same by reason of theprojecting points of the covering and the'head itself engaging theflange h, formed at the top of the groove h, and the projecting pointsof the covering will prevent a knife or other instrument being insertedin the neck of the bottle and engaging the head in such a manner as tohold same up sufficiently to allow the liquid to be introduced into theAs the bottle is tilted the pressure of the liquid against the head 6will force same from o'lf its seat and allow the liquid to flow aroundsame and out of the mouth of the bottle, but when the bottle is againele vated to its vertical position the weighted plunger will again forcethe head 6 on its seat and prevent any liquid being passed into thebottle.

I desire to call particular attention to the simplicity of constructionof this arrangement. The weighted end of the plunger will serve to keepthe head firmly on its seat and prevent any refilling of the bottle;also, that various changes may be made in the details of construction ofmy improved nonrefillable bottle without departing f1O1T1 '[h6 generalspirit of my invention.

Having fully described my invention, what I claim as new, an d desi reto secure by Letters Patent, is-

In combination with a bottle having an annular recess formed inits neckproducing an upper and lower shoulder, a guard composed of a headrounded on its top and having a flat bottom, said bottom being adaptedto lie on the lower shoulder of the recess, a crown or covering for thehead consisting of a convex plate embedded in the head, spurs formedwith the crown or covering around its edge, said spurs being adapted toengage the upper shoulder when the bottle is tilted, a

IO stem formed with and depending from the 'inclosed therein, as and forthe purpose described.

-In testimony whereof I affix my signature in presence of two witnesses.

JACOB M. DOOLIT LE.
